This is the second pre-release from OpenWengo for the WengoPhone 2.1. It includes some major functionality not present in version 2.0, including:

* Secure voice calls using AES 128 bit encryption - thanks to Everbee for this free and open implementation * The ability to configure a SIP account on any SIP server * Massive stability enhancement on Mac and Linux - including hundreds of bug fixes. * Migration to the CMake build system (as used by the KDE project) is complete * Several usability improvements make OpenWengo even nicer to use
